  I hate to say this, but this was done some time ago. I posted 'bundle'
to the net several years ago, it knows about multi-volume, prompts you
for new ones and has the corresponding utility to read the volumes back
in. The latest version also will use shared memory instead of pipes for
double buffering, and so is much faster, but the one in the archives is
still about 3x faster than writing to floppy, even if you only have one.

  The new version is in the comp.source.unix queue, and should be posted
in 2002 at the rate stuff is coming out (I have things in there well
over a year now).
